This tank had an improved armor layout and a hemispherical cast turret which would become the hallmark of post-war Soviet tanks. Despite having thicker armor, it was lighter and stood 30 cm less. This tank is somewhat of a Soviet counterpart of the King Tiger. It is however lighter, faster and more maneuverable, making fast movement around the battlefield possible. The tank is also smaller which aids mobility in urban areas."@en . "IS-3"@en . "Heavy"@en . "In late 1944, the IS-2 was upgraded to the IS-3.

In real life the IS-3 was built so late it never saw any actual combat in WW2 proper, unless impressing the Western Allies during the Allied Victory Parade in Berlin counts. The IS line continued to develop into such vehicles as the IS-7 prototype (which had the size and massof a King Tiger but armament and armour comparable to the 188 ton Maus) and the T-10, the last Soviet heavy tank."@en .
